Question

5) v= 2V A) Domain: { All real numbers. } Range: { All real numbers. } B) Domain: x s 2 Range: y20 C) Domain: x 20 Range: y20 D) Domain: x 20 Range: y so

Answer 1

We will have the following:

*It will have a domain of x equal or greater than 0:

$x\ge0$

It will have a domain of y equal or greater than 0:

$y\ge0$

***

We have the following:

We determine the domain as follows:

Since the function is subject to a root, no negative value can be put in it, so its domain (Since x is not accompanied by any value in the root) can only "hold" values equal or greater than 0.

We determine the range as follows:

Since the function is subject to a root, it's solutions will never be negative, so its range can only hold values equal or greater than 0.
